Power-On Self-Test

The OmniBook 2000, 5500, and 5700 BIOS includes a Power-On Self-Test (POST) facility thattests a number of hardware and firmware items in the unit at each cold-start (BOOT or RESET).

The OmniBook self-test alone should not be used to diagnose a hardware problem. If the self-test results are absolutely clear and repeatable, confirm the results with at least two other non-self-test troubleshooting tools.

Within POST, there are three kinds of messages:• Error Messages – These messages appear when there is a failure in hardware,

software, or firmware.• Informational Messages – These messages provide information to the user but

require no action.• Beep Codes – This kind of warning sounds when POST errors occur and the screen

is not yet available.

Beep Codes

These multiple beep codes indicate a failure in a simple test of:• a portion of base memory• flash BIOS checksum• a portion of conventional memory• a portion of extended memory

If the unit fails to boot• all accessories are removed, including:

memory, floppy drive, docking station, modems and other PC Cards, printers,external displays, pointing devices, and keyboard

• clean AC power is provided (no "chained" battery chargers or auto adapters), andpress reset.

If the unit still fails to boot, it requires service.

Beep codes are used to identify a POST error that occurs when the screen is not available.Once the screen is operating, diagnostic messages are reported to the screen. There are beepcodes for both fatal and nonfatal system board errors.

Display Codes

There are a number of Power On Self Test (POST) tests that are performed after the Beep Codetests. Failure of one or more of these tests will result in a displayed failure code (such as03044). It is extremely important not to interpret a failure code immediately as a hardwarefailure. The failure should be confirmed with a clean boot. A clean boot is defined as pressingthe reset button after removing all accessories (including memory, floppy drive, modems, PCcards, and printers) and providing a reliable power source. Note, make sure the display isadjusted to be visible.

OmniBook Diagnostics

The OmniBook diagnostics program provides a tool for diagnosing and isolating a hardwareproblem. The diagnostics software is intended for use in concert with additional troubleshootingmethods to accurately determine the cause of trouble. The diagnostics program is not designedfor unassisted customer use. Unless otherwise indicated, all diagnostic tests and features areavailable on the OmniBook 2000, 5500, and 5700.

All tests provided in the diagnostics program are designed to run following a clean boot of theOmniBook. This ensures that the environment of the computer will be In a dependable state forthe diagnostics program to properly test the hardware components. The individual tests are non-destructive and are intended to preserve the state of the OmniBook. Reboot after completion ofany test to ensure proper loading of necessary drivers.

Running diagnostics

The diagnostic software must be executed from a DOS command-line following a clean boot.For a system that normally boots to Windows for Workgroups, press F5 at bootup after the BIOSdisplays the CPU speed. This will boot the OmniBook to a DOS command-line. For a Windows95 system, press Shift-F5. The user interface may be invoked or individual tests can be initiatedfrom the command-line. When executed from the command-line, a test may or may not displayresults, but always terminates with either a zero for success or a non-zero for failure (the DOSerrorlevel will be set accordingly). Non-zero results can be unique for each test (a result of 2from a RAM test has a different meaning than a 2 from the serial test).

The diagnostic program is located in the c:\omnibook\diag directory. The main diagnosticprogram (user interface) is invoked by typing diag at the command-line. The main programlooks for executables to perform individual tests using the same path with which it was invoked.For example, if the program was initiated by typing c:\omnibook\diag\diag from the rootdirectory, then the diag directory will be searched for individual test programs.

Logging Test ResultsResults can be logged to a file in the current drive and directory by pressing Alt-L. Only failuresare written to the file. The log file is in ASCII format with the following layout:

date time test label failure description

The main program performs the logging. When logging is enabled for the first time (via thekeyboard), the specified file is opened. If the file already exists, it is truncated. When logging isdisabled or the program is terminated, the file is closed.

Looping TestsAny test, or selection of tests, can be made to repeat or loop. The loop count can be changed bypressing Alt-C. The default count is 1; the maximum count is 9,999. A count of zero (0)indicates infinite looping. The count that is set applies to all tests until DIAG is terminated or thecount is changed again.

Pressing the Backspace key will abort the looping sequence. The diagnostics program will checkthe keyboard for the Backspace key between each test and each iteration. However, since many

30

tests also read the keyboard and discard unexpected key presses, this feature may not work asexpected.

When looping is enabled (count 0 or greater than 1), the date and time is displayed as each testis executed. The timestamp is displayed as the test begins and is over-written at completion.

The DIAG.INI file, located in the c:\omnibook\diag directory, contains a “Loop” entry for eachtest. The value of the entry determines whether the test can be placed in looping mode as partof a group of tests. A value of “1” enables looping in a group, while a ”0” disables this feature.Regardless of this setting, looping will always be available when a test is initiated individually;the Loop entry in DIAG.INI only affects looping on groups of test. In general, group looping isdisabled for the tests that require action by the tester such as the keyboard, mouse, and joysticktests.

User Interface

The main diagnostic program provides a user interface where the following actions can beperformed:

• launch individual or groups of tests• loop through a given set of tests n times or indefinitely• optionally log failures to disk

An example of the user interface screen is displayed below. Note, on the OmniBook 5500, theFull 2 Unit IR and Fan tests are not available. Also, the Internal IR test is referred to as the FastIR test on the OmniBook 5500.

The current test will be displayed in inverse video. The Test message window is an area of thescreen, varying in size, that individual tests use for displaying messages. If used by a test, itpops up and is then removed when the test completes. The Status column is used to display theresults of individual tests. Comments will be used for additional information. Date and Time areused for looping tests.

Interpretation of test resultsThe test results will be displayed in the Status column of the user interface screen. Possibleresults are OK, Done, User Abort, Failed or a brief message indicating the type of failure. OKindicates that the test passed. Done indicates that the test has completed. See Details onIndividual Diagnostic Tests beginning on page 33 for more information on each individual test.

Special test hardware requirements

Several tests within the OmniBook diagnostics program require special hardware. If thehardware is not present, the diagnostics will fail or not function properly. The below table liststhe tests that require special hardware.

Loop Back Connectors

In order to run the RS232 serial port or parallel port self-test, a loop back connector is needed.The loop back may be placed on either the OmniBook port or at the end of the correspondingcable. This feature is also helpful in diagnosing a defective serial or parallel cable.

Loop back connectors may be purchased or easily constructed. The following illustrationsidentify the correct pin-out configurations for the serial and parallel loop back connectors.

Details on Individual Diagnostic Tests

This section explains each test within the diagnostics program. Each test is listed along with itscommand-line file name. A brief description of the test, command-line parameters, validkeystrokes available during the test, and corresponding failure messages with error codes arealso given.

Note, the term “flushed” that is used in the keystrokes sections indicates that the key is read fromthe key buffer and then discarded.

Test AllThis is an easy way to run all the tests in sequence. However, looping does not work asexpected with the Test All selection. For example, if three tests are tagged for looping and TestAll is initiated, then the first two tests are executed only once. The last test in the sequence isthe only test that will be looped.

Display - (DISP.COM)The Display test executes a sequence of patterns on the screen:1. Tests video RAM, which leaves vertical lines in groups of 4.2. Draws a box around the outside edge of the display, filling the center with black.3. Fills the entire display with white.4. Fills the entire display with a 10-pixel checkerboard.5. Fills the display with horizontal lines on every 4th pixel, then steps the lines 3 times.6. Fills the display with vertical lines on every 4th pixel, then steps the lines 3 times.7. Draws 16 horizontal bars of different colors.8. Draws 16 vertical bars of different colors.9. Draws 4 horizontal shaded bands (red, green, blue, and white) with vertical tick marks.

DOS Parameter Explanation1, 0, or none Wait for a key after each display pattern2 or greater Don’t wait for a key

Failed 5 Receive fail or any other fail.

36

Full 2 Unit IR Test - (FIRTEST.EXE)The Full 2 Unit IR test is not available on the OmniBook 5500. This test requires twoOmniBooks: one on which the IR is known to be good, and the computer to be tested. Thecomputer that is being tested will transmit IR packets to the known good computer, which willtransmit (reflect) the packets back. This method ensures both transmitting and receivingfunctions are checked on the computer under test.

The test checks 115200 baud, 1.152 Mbps, and 4 Mbps by sending 20 packets at each speedand looping through the 3 speeds three times for a total of 60 packets at each speed. Everyreceived packet is checked byte for byte against the packet that was sent. Every packet mustpass or the test will fail.

To run the "Full 2 Unit IR" test, perform the following steps:

1. Clean boot both computers.Windows 95 -- reboot and press shortly before or after the

computer displays "Starting Windows 95".Windows for Workgroups -- reboot and press while the boot menu

is displayed.

After clean booting, change to the c:\omnibook\diag directory.

2. Prepare the known good computer to reflect packets to the test unit.Run DIAG.EXE and highlight "Full 2 Unit IR" and press + . (When desired testing duration iscomplete, press any key to abort the reflecting end of the test.)

3. Position the computer to be tested so that the IR port is in line with the IR port on theknown good unit. For a simple pass/fail test, run DIAG.EXE, highlight "Full 2 Unit IR"and press .

DOS Parameter ExplanationInternal Performs the internal (standalone) loopback

test. This option does not test as much ofthe IR hardware, but will work with just onecomputer. Do not use this parameter withany of the other parameters.

Reflect Initiates the "known good" reflecting end ofthe full 2 unit test.

Baud=xxxxxx Sets the baud for the first speed tested(defaults to 115200 baud). Unless/PHYTEST is also used, the 1.152M and4M speeds will always be tested. Type inthe full number for the baud to be tested(type 1152000 for 1.152Mbps, 4000000 for4Mbps). Note -- This parameter must beused on both the known good reflectingcomputer and the computer under test.Both computers must start at the samespeed to be able to communicate.

Loops=xxxxx Sets the number of times to loop through

37

the 3 speeds under test. Default = 3.Phytest Limits the test to just one speed which can

be set with /BAUD. It also uses all nullbytes rather than random data. Defaultspeed = 115200 baud

Desktop Management Interface (DMI)

The Desktop Management Task Force (DMTF) was founded in 1992 by a group of leadingcomputer manufacturers, including Hewlett-Packard, to define a standard method of managingthe physical and logical components of personal computers. The result of these efforts is theDesktop Management Interface (DMI). The DMI package is pre-installed on the OmniBook 2000and 5700.

Description of DMI

DMI is basically a set of rules for accessing information about a personal computer. Using DMI,an application program can determine, for example, which hardware and software componentsare present in a personal computer, the operating system that is being used, and the number ofaccessory board slots that are available. Using the DMI interface, a local or remote applicationprogram can check what hardware and software components are installed on your computer,how well they are working, and whether any needs replacing.

All this information is stored in a special Management Information Format (MIF) file, installed oneach personal computer as part of the DMI package. The MIF file specifies information aboutcomponents at two levels:

• Groups contain all the information concerning a particular hardware or softwarecomponent. If more than one component of the same type is present, as is often thecase with serial ports and hard disk drives, a group is repeated.

• Attributes are specific items of information relating to a group. Attributes of the Mousegroup, for example, include the number of mouse buttons and the name and versionnumber of the mouse driver being used.

Hewlett-Packard has developed a number of extensions to DMI to allow the enhanced featuresof HP OmniBook Notebook PCs to be managed with DMI. These extensions cover:

• Administrator and user passwords.• Tattooing: a string of characters that uniquely identifies the computer.

Note: The DMI software package included with the OmniBook can only be used with the HPOmniBook Notebook PC.

For full details of the structure of the MIF file, including an explanation of the meaning of thefields of groups and attributes and how to write an application program that accesses thisinformation, you can access the DMTF FTP server ftp.dmtf.org or the DMTF Web Pages at theURL www.dmtf.org .

Contents of the DMI Package

The DMI software and associated documentation is supplied either pre-installed on theOmniBook's hard disk drive or on two flexible disks. The contents of the package are the samein both cases.

Since the information accessed by the DMI software is specific to a particular computer, it mustbe installed on each computer separately.

46

The following software is supplied with the DMI package:• A Microsoft Windows utility, SETUP.EXE, to install and initialize the DMI software.• A Windows utility, HP TopTools. After DMI is installed, this utility can be used to display

information about the computer through the DMI.• A Management Information Format (MIF) file. This file contains information about

everything on the computer that can be controlled using DMI facilities, and is initializedduring installation.

• A component code, identifying the version of MIF file to use for specific models of HPOmniBook Notebook PCs.

• Windows-compatible DMTF Service Layer software, which controls access to the DMI.• A client agent. The HP Remote DMI Agent is a DMI application and also a network

server-side stream-based application. The Remote Agent is listening for RemoteApplication connection requests. If the main window of the Remote Agent is hidden, thenno icon will appear on the screen when it is running.

Figure 11 provides a visual representation of the many components of the DMI package.

Installing the DMI Package from Windows 95The DMI package is included with the OmniBook, but it must be properly installed before it canbe used. The following steps explain how.

Alternatively, to install the DMI from floppy disks:• Copy the DMI software from the \omnibook\dirvers\win95\dmi directory of either the hard

disk or Recovery CD to two floppy diskettes (copy the contents of the \disk1 subdirectory todiskette #1 and the contents of the \disk2 subdirectory to diskette #2).

• Start Windows 95, if it is not already running.• Insert diskette #1 into the floppy drive.• Select and run the SETUP program from the diskette #1.

To install the DMI preloaded on the hard disk:• Start Windows 95, if it is not already running.• Click on "Start".• Go to "Programs - HP DMI".• Select and run "SETUP".

Uninstalling the DMI Package from Windows 95• Go to the HP DMI group.• Launch the program "Uninstall DMI".• Reboot the PC.

Using the DMI InterfaceFor a complete explanation of how to fully take advantage of DMI, the following documentationis provided with the OmniBook:• A README.TXT file.• A Windows online help file describing Hewlett-Packard's implementation of DMI (group and

attribute definitions). Since not all Hewlett-Packard enhanced features are supported on allmodels, this document also describes any restrictions that apply.

System Configuration Utility

The System Configuration Utility (SCU) can be used to troubleshoot both software and hardwareissues. Settings in the SCU may cause unexpected results in the operation of the OmniBook orinstalled applications. Battery charge and other system settings also can be verified with theSCU. The SCU settings are identical for the OmniBook 2000, 5500, and 5700, except wherenoted below.

The SCU is operating system independent and can be accessed by pressing F2 at boot-up orFn+F2 at any other time. Use the key to activate the menus and the cursor keys tonavigate. The left mouse button, spacebar, and key can also be used. The right mousebutton and the key will cancel the current action.

Main Configuration Screen

The main configuration screen of the SCU reports several system settings. See Figure 12 for anexample of the main screen. The reported settings cannot be modified from the main screen;the changes must be made from the corresponding menu.
